HI，

我有64位DLL，而我有32位dll，我无法重新编译.

I have 64 bit DLL and I have 32 bit dll that I can't re-compile.

我想从我的64位dll调用一个方法转换为32位DLL.我尝试使用LoadLibraryEx()，但是getProcessAddress不起作用.

I want to call from my 64 bit dll a method into 32 bit DLL. I try to use LoadLibraryEx() but then the getProcessAddress doesn't work.

我该怎么办?

代码是:

typedef int (*startOrder)(); HINSTANCE hLib = LoadLibraryEx(L"my32bit.dll", NULL, LOAD_LIBRARY_AS_DATAFILE); //acutPrintf(L"\nLoadLibraryEx"); startOrder start; if (hLib !=NULL) { //acutPrintf(L"\nLoadLibraryEx != NULL"); start=(startOrder)GetProcAddress(hLib,"StartOrder"); if (!start) ; else { start(); } FreeLibrary(hLib); } else { //Printf(L"\nLoadLibrary == NULL"); }

推荐答案

您不能将32位DLL加载到64位中过程.那是行不通的.

You cannot load a 32bit-DLL into a 64bit process. That will not work.

您唯一可以做的事:

1.开始一个新的加载32位DLL的32位进程

1. Start a new 32-bit process which load the 32bit DLL

2.与64位和32位进程之间的InterProcessCommunication进行通信.

2. Comunicate with InterProcessCommunication between the 64 and 32bit processes.
